Problem this snippet solves:

Summary: This iControl script will bulk create NATs based on the contents of an input file.

This iControl script will read the contents of an input file containing nat origin:destination pairs and bulk create NATs based on those values.

How to use this snippet:

Syntax

NAT.pl bigip port username password create input_filename

NAT.pl bigip port username password delete_all

Input File: NAT.txt

1.1.1.1,2.2.2.1

1.1.1.2,2.2.2.2

1.1.1.3,2.2.2.3

1.1.1.4,2.2.2.4
